Abstract

The invention provides an impulse turbine. The impulse turbine comprises an integrated machine case base which is of a box body structure defined by a bottom plate, a side plate, a cover plate and twopanels arranged front and back and is inclined towards the side plate; a rotating wheel is arranged between the two panels; a first mounting base and a second mounting base are arranged on the coverplate and the side plate correspondingly; the first mounting base and the second mounting base are provided with direct current spray pipes correspondingly; the two direct current spray pipes communicate with an external water conduit through a pipeline; the cover plate is provided with a drainage plate; and the two panels are provided with inspection holes for inspection of the rotating wheel, and end covers matched with the inspection holes. According to the impulse turbine, the structure of the machine case base is optimized, split faces do not need to be arranged, the jet direction precision is high, and the problems that traditional machine case base structures are manufactured in a split mode and are high in machining workloads, and joints are sealed unreliably are effectively solved; and the two panels are provided with the inspection holes for inspection of the rotating wheel, and the end covers matched with the inspection holes, so that the demands of dismounting, mounting andmaintenance of the rotating wheel are met.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an impact water turbine, in particular to a horizontal double direct current nozzle impact water turbine, which is used to install and fix the nozzle, ensure the relative position of the nozzle and the runner, and turn the runner The water flow thrown by the bucket blade is introduced downstream. Background technique [0002] The impact turbine is a hydraulic prime mover that uses a special water guide mechanism to draw a free jet with kinetic energy, rushing to the water bucket of the runner, and making the runner rotate to do work, thereby completing the conversion of water energy into mechanical energy. Pelton turbines are suitable for power stations with high water head and small flow. The impact turbine is a turbine with a high water head (water head exceeding 300-500m). The flow is introduced from the pressure water pipe through the nozzle, and the potential e...
